Mass Transit

Mass transit using trains and subways can be one of our greatest conveniences or biggest frustrations! We want to be on time, and more importantly, we need to be safe. Power quality and battery backup systems play an important role in meeting these two objectives.

The primary use of battery backup is to maintain uninterrupted power to critical controls for ventilation fans and water pumps, as well as status/warning lights for train personnel. Track-side telemetry and security/surveillance systems are also key areas of concern requiring uninterrupted power.

We have a number of product solutions that provide power conditioning and line voltage regulation, as well as uninterrupted power for critical controls and monitoring systems!
